The sunflower sea star (Pycnopodia helianthoides) is highly susceptible to sea star wasting disease. The authors of a 2019 paper published in Science Advances document the rapid, widespread decline of sunflower stars and discuss the ecological implications of losing this important subtidal predator species.

A study in the journal PLOS ONE uses volunteer diver surveys to assess the impacts of sea star wasting disease in the Salish Sea. Data shows that sunflower sea stars were especially hard hit and have all but disappeared from the region.
